I used FFOF too for the first 8 months or so of my growing experience. After FF opened a new plant on the east coast to manufacture the ocean forest, they started using ingredients (read: pine bark) that altered the smell, feel, and water retention capabilities of the soil. So I switched to BioBizz Light Mix, which is peat moss, sphagnum peat and perlite. I mix that in a 3:1 ratio with Fox Farm Light Warrior and add a few tablespoons of 9-3-2 bat guano and a healthy amount of 1-0-0 worm castings. I also add a little perlite, as the BB Light Mix seems to be a little deficient in this area.
My plants love it...way less "hot" than ocean forest and like someone else said, I get to control all the nutrients going in and out of the pot, making it very easy to identify and address problems.
To the OP, you should have added more categories for your poll...
